Upper panel: Same as Fig. 2 but for the simultaneous best fit model (= 2P_{(1218 d-ecc, 2.27 d-circ)}) of the two planetary signals around G 192–15. Lower panel: RVs over time for the same model. The black lines show the model based on the parameters listed in Table 3, and the gray shaded areas denote the 68%, 95%, and 99% confidence intervals, respectively. The instrument offset of CARMENES was subtracted from the measurements and the model.
